Title: Electric circuit breaker operating mechanisms
Inventor: MILLS DONALD C
IPC: H01H3/30
Filed: 1957-10-25
Abstract: 819,028. Automatic circuit-breakers. FEDERAL PACIFIC ELECTRIC CO. Oct. 25, 1957, No. 33441/57. Class 38 (5). The moving contact arm 16 of a circuit-breaker is coupled by a rod 20 to a driven member 24 carried on two arms 26 pivoted at 28 which is also the pivotal axis for a driving member 32. The latter has a shaped face 32a which, when the member 32 is moved by a solenoid plunger 38, engages a roller 50b on a latching member 50 so as to tend to rotate the member 50 in a clockwise direction (anti-clockwise in Fig. 1) about its pivot 52 on the member 24. However, a pivot pin 50d on a leg 50c of the member 50 is retained at the axis 28 by a link 88 of a release mechanism so that the member 24 is rotated to close the breaker (Figs. 1 and 4). In this position the member 50 is retained by a latch 68 pivoted at 70 and biased by a spring 78 on a stop bolt 72. The latch 68 carries a leaf spring 76 for operating a snap-action switch 82 and having two arms 76a, 76b with a doubleheaded rod 84 to limit the degree of separation of the arms. As the roller 50b is moved toward the final closed position it lifts both the latch 68 and arm 76b to the dotted line position shown in Fig. 5. The switch 82, however, is not operated since the looped end of the spring 76 on a pin 74 is moved downward, but when the latch 68 drops into the latched position (Fig. 4) the switch 82 is operated by the upper arm 76a. The switch 82 is arranged to cause disconnection of the solenoid so that the plunger 38 and member 32 are retracted by springs (not shown). The link 88 of the release mechanism is connected to a centrally-pivoted lever 90 retained by series toggles 92, 94 and 96, 98 which are in turn retained by an armaturelatch 100 trippable by an electromagnet 102. The circuit-breaker opening springs (not shown) act on the member 24 so that when the pin 50d is allowed to move by the release mechanism, member 50 rotates clockwise to disengage the latch 68 and the circuit-breaker opens. The release mechanism is reset by a spring 104. The member 24 also operates an arc-blow-out air puffer.

Title: Separation of hydrocarbons by means of molecular sieves
IPC: C10G25/03
Filed: 1958-10-20
Abstract: In the separation of hydrocarbons by selective adsorption of one component of a mixture on a molecular sieve and subsequent desorption of the adsorbed component by heating the sieve with a heated recycle stream of desorbate followed by reduction of pressure the pressure is reduced to below 300 mm. of mercury after the adsorption period and before heating.  Normal paraffins may be separated from other hydrocarbons using a 5  sieve having a pore volume of about 0,25 cc. per gram.  Adsorption is preferably effected in the vapour phase at 200-400 DEG F. and 0-50 p.s.i.g. and 0,3-2 w/wHr, the feed being first dried, e.g. by passing through a 4  or 5  molecular sieve or through silica gel.  Desorption may be affected by heating to 500-1000 DEG F. followed by reduction of pressure to about 100 mm. The reduction of pressure prior to heating removes surface adsorbed non-normal hydrocarbons and may be applied for about 15 minutes.ALSO:In the separation of hydrocarbons using a molecular sieve the heated stream of desorbate which is used to remove further absorbed gases is preceded by a vacuum treatment of the sieve after the discontinuation of the hydrocarbon feed.  Sieve material of 4 and 5  pore size is generally used with pellets of 1/16 to 1/8 inch diameter and 3/16 inches in length and pore volume of 0.25 c.c. per gm.

Title: Method of and apparatus for conditioning cheese curd
IPC: A01J25/11
Filed: 1965-08-06
Abstract: In a method for preparing cheese curd for curing and to cause at least partial knitting of the cheese curd, including pressing of the discrete curd granules and delivery of the pressed curd into a receptacle, the pressing of the curd is of a character to cause at least partial knitting of the granules into a flowable mass, which is thereafter caused to flow and stretch without substantial rupturing of the knitted mass, for example by causing the mass to undergo a controlled change of dimensions.  Whey may be expelled from the granules during the pressing, which may be carried out in two stages, the second stage being at a higher pressure.  Prior to the pressing the granular mass may be subjected to a vacuum.  The pressing step may include the formation of an annular recess in the upper surface of the mass. After the mass has been caused to flow and stretch, it may be subjected to a further pressing step, preferably with application of heat.  A suitable apparatus comprises a tower, with a forming tray of larger area than the cross-section of the tower positioned beneath the tower, the tower having draining slots, within which the granules are subjected to pressure via a pressure plate. The flow and stretch is then effected by moving the tower and forming tray apart at controlled rate.  The tray is preferably square, and the tower is preferably of four pointed star cross-section, such that the distance between the corners of the tray and the points of the star is substantially the same as the distance between the sides of the tray and the valleys of the star.

Abstract: 1,057,036. Cathode-ray tube viewing devices; radar. TECHNION RESEARCH & DEVELOPMENT FOUNDATION Ltd. Aug. 27, 1963, No. 33872/63. Headings H4D and H4T. [Also in Divisions G2 and H1] In an arrangement for producing a 3-dimensional pictorial display a picture is effectively produced or reproduced on a rotatable display member having one or more helical display surfaces formed about a common axis. Fig. 1 shows one embodiment in which the picture, consisting of a P.P.I. display on the screen of a short-persistence cathode-ray tube 6, is viewed through a display member 8 formed (preferably by a disc of fibre optic material) to have a single helical display surface (which is also radially concavely curved, Fig. 2 (not shown)) and a rear surface of the same configuration as that of the tube screen. The member 8 is rotated about its axis (which forms an extension of the longitudinal axis of the tube) by a gear mechanism 9 driven via a mechanical adder 11 which adds the speed of the vertical scanning mechanism 3 of the radar antenna (about twenty sweeps per second) to the speed of the azimuthal scanning mechanism 2 (about four revolutions per minute) the latter, alternatively or additionally, being controllable by manual means 5. The member 8 makes a complete revolution for each vertical scan of the antenna (the scan to-flyback time of which is in the ratio of 5 : 1) so that in the resultant display targets having different elevations appear on member 8 in positions of 'different thickness and thus elevation is manifest as a third dimension. The height of targets may be estimated by providing equi-height contour lines on the member 8, Fig. 4 (not shown), although for precise measurement the conventional manually controlled electronic range and height markers must be utilized. The member 8 may be remote from tube 6 and the display on the latter projected on to the non-helical surface of the member by a lens system or, on to the helical surface if the latter is formed as a reflecting surface. Alternatively, member 8 may form part of the structure of the cathode-ray tube in which case the non-helical surface is provided with a short-persistence phosphor.

Filed: 1973-07-17
Abstract: 1445846 Bar code reading system NORAND CORP 17 July 1973 34067/73 Heading G4M [Also in Division H3] A reading system for a bar code in which bars have two possible widths each of two possible characteristics decodes bars of one of the widths and either polarity as one binary digit and the other width and either polarity as the other bit. In an optical embodiment signals from a light detector are amplified and passed through a circuit providing amplitude and level control and feeding a cross-over detector which clips the level controlled signal to remove negative levels, to square the signals and produce true and inverse pulses (Fig. 3, not shown). The true and inverted pulses feed flip-flops which via a switching delay produce pulses occurring for each cross-over point of the signal (Fig. 7a, not shown). The amplified signal from the detector is applied 67 to a peak detector (Fig. 4) where diode 69 supplies a negative rectified wave and diode 70 supplies a D.C. level 72 via capacitor 73 charged to the negative peak of the waveform. In attenuated D.C. level 72a is fed to operational amplifier 80 which also receives the signal 71 from diode 69 to produce a series of pulses corresponding 81 to the periods when the peak of the waveform from diode 69 exceeds the attenuated level from diode 70 and corresponds to the detection of wide white bars. Diode 92 rectifies the signal on line 67 to pass black bar information and pulses from a flip-flop representing squared data pulses (Q62, Fig. 7a, not shown) are fed on line 68 to charge capacitor 97 which will be charged by wide bars to a value twice that achieved for narrow bars, 99, Fig. 7b. The two signals are summed and compared with a reference 108 which is situated between the peaks of the wide and narrow bar signals regardless of variations in reflectivity of the black bars to produce pulses corresponding to the wide black bars. The white and black bar signals are fed to OR gate 86. The data signals and the cross-over pulses are fed via shift registers (Fig. 5, not shown) to a display unit and to START and STOP code detectors. A counter (Fig. 6, not shown) counts the number of bits in each digit and the number of bits in six digits which is the amount displayed. An audio alarm is produced if an error in the number of bits occurs or if a STOP code is not received. The gates in the logic circuitry are enabled when the probe is placed against the document. It is stated that a detector for magnetic markings may be used.

[Class 40 (i).] An electro-mechanical device for indicating movements at a distance, more particularly applicable to liquid level indicators, of the kind described in Specification 284,277, [Class 37, Electricity, Measuring &c.], comprises a float actuating a contact arm 5 over a resistance 4 which decreases from the centre towards the edges. Both ends of the resistance and the arm 5 are connected to a receiver comprising a coil with two unequal windings 10, 101 in series connected so that their fields are in opposition, and surrounding a fixed half ring of iron. A coil 12 is adapted to polarize a blade 13 carrying a pointer 13<1>. When the arm 5 is at the point 8 of the resistance, the latter is wholly in circuit and is in parallel with the coil 10, the current in which is thus only slightly decreased. The resultant field of the coils 10, 10<1> causes the blade 13 to move to the end of the coil. Movement of the arm 5 along the resistance 4 decreases the resistance in parallel with the coil 10 and decreases the current in this coil and the corresponding field strength. The blade 13 is thus moved towards the centre. A small iron plate 7 is provided for adjustment.
